But there's another issue in this case that, as a physician, I feel merits more attention: the importance and indeed revolutionary nature of the rule. Between 2007 and 2011, my colleagues and I conducted a study that shows that improving access to contraception promises to reduce our nation's unintended pregnancy and abortion rates dramatically. It isn't hard to understand why.

Birth control lets women determine whether and when to have children. But that's not all. Women also need contraceptive care for other medical reasons, such as preventing ovarian or uterine cancer and regulating painful periods. There's a reason why the Affordable Care Act includes contraceptive care at no cost to the individual -- it's basic health care.

We also know that cost is a factor in what contraception women use. Nearly one-third of women say they would change their contraception method if cost were not an issue.

During this long-term study, we offered more than 9,000 women the reversible contraceptive method of their choice while at the same time improving their knowledge of contraceptive methods and eliminating the most common barriers women face: cost and access. The results demonstrated the extraordinary promise of giving women the tools they need to control their reproductive lives.

This figure radically differs from the contraception chosen by women in the current landscape. Far fewer women in the general population use these methods, in large part because they are expensive.

Our study suggests that when we remove cost barriers and improve education and access, as would be the case with full implementation of the contraceptive rule, we have the potential to make an astounding impact on the public health of women in our country.

Wouldn't it be great if an unintended consequence of this mandate was a reduction in the number of unintended pregnancies and the need for abortions?

Meeting the contraceptive needs of women will never be achieved when all methods of birth control are not equally accessible to every woman.
